Answer:

66.67 %

Step-by-step explanation:

As we can see from the figure

We are given a bar graph in which bars represent the number of reserved campsites at a camp ground for one week from Monday to Sunday.

First of all

Lets the count the total number of reservations made by campsites during the week.

Total Number of campsite reservations = 5+3+4+7+26+30+9

Total Number of campsite reservations =84

Now

we have to calculate what percent of reservations were made for friday or saturday.

% of reservations made on friday or saturday = frac{total-numer-of-reservations-on-friday-or-saturday}{total-number-of reservations}

% of reservations made on friday or saturday = frac{26+30}{84}

% of reservations made on friday or saturday = frac{56}{84}

% of reservations made on friday or saturday = 66.67 %

So in total 66.67 % reservations are on friday and saturday.
